3.03 Primary Input Power
Connections
CAUTION
Check your power source for correct voltage be-
fore plugging in or connecting the unit. Check the
Voltage Selector at the rear of the unit for correct
setting before plugging in or connecting the unit.
The primary power source, fuse, and any extension
cords used must conform to local electrical code
and the recommended circuit protection and wiring
requirements as specified in Section 2.
Most units are shipped from the factory with a
460Volt input power cable wired to the input
contactor in the single - phase configuration.
The following illustrations and directions are for
changing that configuration to a different voltage
and or to three - phase operation or back again if a
change had already been made.

NOTE
There is only one jumper setting that changes
between the single and three phase settings. To
change from single phase to three phase, the
jumper connected to L2 needs to be removed and
placed on the other L3 connection so both ends
of the jumper are attached to the same electrical
point. See previous illustrations.
